Overview of A2 Tool Steel
A2 Tool Steel, designated under AISI classification, is an air-hardening cold work tool steel with high wear resistance and excellent dimensional stability during heat treatment. It is widely used in stamping dies, forming tools, and cutting instruments. Compared with oil-hardening O1 steel, A2 offers better toughness and stability, making it one of the most popular choices for precision tooling.
A2 Tool Steel:Chemical Composition (Typical, %)
- C (Carbon): 0.95 – 1.05
- Cr (Chromium): 4.75 – 5.50
- Mo (Molybdenum): 0.90 – 1.40
- Mn (Manganese): 0.40 – 1.00
- V (Vanadium): 0.15 – 0.50
- Si (Silicon): 0.10-0.50
This alloy balance provides excellent hardness (up to 62 HRC after hardening) and reliable wear resistance while retaining reasonable toughness.
A2 Tool Steel:Key Features
- Air-hardening steel → reduces risk of cracking or distortion during quenching.
- Good dimensional stability → suitable for precision dies and tools.
- Balanced wear resistance and toughness → better than O1, less brittle than D2.
- Ease of machining (annealed condition) → allows efficient tool manufacturing.
- Long service life in tooling applications under moderate to high stress.
A2 Tool Steel:Heat Treatment Process
- Annealing: Heat to 845–870°C, then slow cool at ≤20°C per hour to 650°C.
- Hardening: Preheat at 790–820°C, then austenitize at 955–980°C.
- Quenching: Air or inert gas cooling.
- Tempering: Usually double tempering at 150–500°C depending on required hardness (final hardness 57–62 HRC).
Applications of A2 Tool Steel
- Blanking & Punching Dies
- Cold Shear Blades
- Forming and Bending Tools
- Gauges & Fixtures
- Knives and Cutting Tools
- Industrial Shears
A2 steel is especially popular in general-purpose cold work tooling where both durability and dimensional accuracy are required.
